Log Message:
quakeforge: The existing workaround is causing duplicate symbol errors at
link-time so just cheat by using "static inline".

Also, don't hardcode the libGL version number, take advantage of symlinks
instead to make libGL load on NetBSD-current with native X.

Bump PKGREVISION.

I still can't really get this to run for more than a few seconds (except
qw-client, which I can't test ingame), it may be borked.
